【摘要】 提出一个适用于船舶初步设计阶段计算船舶操纵运动水动力的方法，给出了与船体表面局部线型相关的非线性力的估算方法。通过对方型系数Cb值为0.57～0.835艘船模的具体计算，结果表明与其相应的约束模试验结果吻合良好。本文方法可用于操纵运动数值模拟，也能作为港内低速大漂角航行船舶的运动模拟。更多还原

【Abstract】 The method proposed in this paper is suitable for evaluating the hydrodynamic forces acting on a maneuvering ship at the initial ship design stage ,in which the nonlinear forces depends on the local hull lines. The detailed calculation was carried out for five ships with Cb of 0.57～0. 83. The calculation results show good agreement with the corresponding captive model test results. The method described in the paper can be used to simulate the ship’s maneuvering motion,and it is also appropriate to simulate the ship motion with large drift angle at low speed in the port.更多还原
